java - 在第一周之后打印日历月的剩余时间

Question

我正在制作一个程序，该程序在 1-12 月和开始日读取，1-7 表示星期日、星期一等。它打印第一周很好，但我在打印第一周后的其余几天时遇到问题。它不会将输出格式化为在其余天之间留有空格，仅在第一周后的第一天。

旁注：键盘是我的项目中包含的一个类

这是我的代码：

import java.io.*;

public class CalendarMonth 
{
    static final int WEEK = 7;

    public static void main(String[] args) throws IOException
    {
        String proceed;
        char repeatCheck;
        int days;
        String leapYear;
        char leapYearCheck;
        int startDay;


        do
        {
            days = getDays();



            System.out.println(days);

            System.out.println("Please enter a number 1-7 that the month starts on: (1 for sunday, 2 for monday, etc)");
            startDay = Keyboard.readInt();


            while(startDay < 1 || startDay > 7)
            {
                System.out.println("You did not enter a number 1-7, Try again: ");
                startDay = Keyboard.readInt();
            }

            System.out.println(" s m t w th f sa");

            printMonth(days,startDay);
